Editing Excimer laser (section)

=== Wavelength determination ===
The [[wavelength]] of an excimer laser depends on the molecules used, and is usually in the ultraviolet range of [[electromagnetic radiation]]:

Excimer lasers, such as XeF and KrF, can also be made slightly ''tunable'' using a variety of prism and grating intracavity arrangements.<ref>[[F. J. Duarte]] (Ed.), ''Tunable Lasers Handbook'' (Academic, New York, 1995) Chapter 3.</ref>
